CVE-2007-4033

Published: 27 July 2007

Buffer overflow in the intT1_EnvGetCompletePath function in lib/t1lib/t1env.c in t1lib 5.1.1 allows context-dependent attackers to execute arbitrary code via a long FileName parameter. NOTE: this issue was originally reported to be in the imagepsloadfont function in php_gd2.dll in the gd (PHP_GD2) extension in PHP 5.2.3.

From the Ubuntu Security Team

It was discovered that t1lib does not properly perform bounds checking which can result in a buffer overflow vulnerability. An attacker could send specially crafted input to applications linked against t1lib which could result in a DoS or arbitrary code execution.

Notes

while tetex-bin and texlive-bin have embedded t1lib code, it's
not used
